Perlite Plaster or External Thermal Insulation (Mantolama)? Which One is More Advantageous?
One of the most frequently asked questions by those who want to have thermal insulation is: Is perlite plaster or external thermal insulation (mantolama) better?
In this article, we compare the two methods in detail and explain which one is more advantageous in which situations.
What is Perlite Plaster?
Perlite plaster is a cement-based, lightweight type of plaster with perlite additives.
Thanks to perlite, it:
- Provides thermal insulation
- Contributes to sound insulation
- Allows the wall to breathe
- Does not add extra load to the structure
It is especially preferred as a practical insulation solution for interior and exterior facades.
What is External Thermal Insulation (Mantolama)?
External thermal insulation (mantolama) is a classic insulation system performed by applying thermal insulation boards (EPS, XPS, etc.) to the exterior facades of buildings.
Purpose:
- To minimize heat loss
- To provide energy savings
- To protect the building from external factors
Perlite Plaster vs. External Thermal Insulation: Comparison
1. Thermal Insulation
- External Thermal Insulation: Provides lower thermal insulation
- Perlite Plaster: Provides higher thermal insulation
Result: If you want maximum insulation, perlite plaster is ahead.
2. Sound Insulation
- Perlite Plaster: It is a better sound absorber thanks to its porous structure.
- External Thermal Insulation: Sound insulation is limited.
